The Calmark product line offers a wide variety of standard finishes for products. Most of the components are made of aluminum or stainless steel. The standard finishes are: For Aluminum, standard finishes include: For BeCu, standard finishes include:

• Chemical Film per Mil-DTL-5541 Type 1 (non-RoHS) Class 1A or 3, Gold • Tin Plate per Mil-T-10727 Type I, Bright

• Chemical Film per Mil-DTL-5541 Class 3, Type II, Clear • Nickel Plate per QQ-N-290 Class I, Grade F

• Black Anodize per Mil-A-8625 Type II, Class 2 • Electroless Nickel per Mil-C-26074 Class 4, Grade B, Bright

• Hard Black Anodize per Mil-A-8625 Type III, Class 2 • Zinc Plate per ASTM-B633 Type III (Clear), SC1

• Electroless Nickel per Mil-C-26074 Class 4, Grade B, Bright For Nylon card guides and extractors:

For Stainless steel, standard finish is:• Color coding is available for Natural/White card guides and extractors

• Passivation per AMS 2700• Standard colors are BLK and Natural; other colors avalailable upon request.

The Calmark product line offers several product configurations to meet the requirements of the European Directive 2002/95/EC for Restriction of Hazardous Substances. This European Directive affects primarily the aluminum components that are finished with a gold chemical film process. This process uses a hexavalent chromium (Cr+6). An option for clear chemical film process using a trivalent chromium (Cr+3) has been added for those needing to meet this requirement. Contact one of our applications engineers for more details regarding the RoHS requirements of specific items.

Calmark products can support the needs of Prime Contractors and Subcontractors supplying product to the DOD, particularly the Preference for Domestic Specialty Metals Clause. This clause is applicable to DOD Prime Contract Awards exceeding the simplified acquistion threshold, of products, components and assemblies for use in Aircraft, Missile and Space Systems, Ships, Tank and Automotive Items, Weapon Systems or Ammunition. For the Calmark product line, this affects the hardware, components and materials that are made of stainless steel. At the time of this writing, all COTS items which include all part numbers configurable in this catalog are exempt from the Preference for Domestic Specialty Metals Clause for Prime Contract Awards after October 25, 2007. Fastener DNAD waivers are also available for Prime Contract Awards between April 10, 2007, and July 26, 2008. There are many other exemptions available.

We recognize that each of our customers has a different method for handling this requirement, so we have implemented a process that we feel will handle the great majority of our customers’ requirements. Because at this time, the Class Deviations are not retro-active, in order to best respond to your needs, we do require that all quotations and purchase orders note this requirement along with the Prime Contract Number. We do charge for a signed DFARS 252.225-7014 & Alt 1. Statement Sheet that must go along with your order. For those customers that can use the COTS exemption, we offer free of charge documents that you can download from our website. The Product Sheets will indicate from the Statement Sheet which statement applies for your product of interest. If these documents meet your needs, please indicate this in your quotation or P.O. Of course, for those customers that need a signed Statement Sheet, we can also accomodate this requirement at an additional fee.

Calmark also provides as a standard offering products that meet many of the specifications defined by Defense Supply Center – Columbus. Calmark has incorporated the DSCC part numbers as a standard product offering to get the proper specification requirements by the addition of a “CM-” prefix to the DSCC part configuration for our internal part number system. The DSCC part number will be part of the description. All part numbers defined in the DSCC specifications are considered COTS items for Calmark.

The Calmark product line offers an extremely broad range of configurations, not all of which are detailed in this catalog. Calmark is set up to handle these requests. Contact one of our Applications Engineers and a unique part number will be assigned for you for a product that meets your specification. Some of the modifications available include: • 7 and 9 or more wedge segments • Different lever lengths than those offered in the catalog • Lengths outside of our standard catalog product offering • Different hardware than standard offering including screw threads, thread-

locking mechanism and bonded washers • Relocation or addition of mounting holes • Tapped holes other than the standard catalog product offering • Secured wedges • Screw head activation different from M2.5 and 3/32 hex socket • Ejection feature simillar to E225 may be implemented on other • Specific individual wedge dimensions different from the

catalog offering Series profiles

• Modification of extractors • Replacement of split washers with Belleville washers • Hot stamp of plastic parts to your requirements • Materials with different alloys from the catalog offering • Silkscreen per your requirements

• Add chamfers• Different finish from those offered in the catalog Our applications engineers can help you specify a cost effective design that will work for your application. The catalog offers the configurations that meet most applications, but if you don’t see what you’re looking for in the catalog, please call us. Odds are, we’ve already done something very similar.

Pentair Technical Products’ Warranty is guaranteed from defects for 1 (one) year after shipment.

Technical ApplicationsDiscussion

CARD-LOK For cold wall applications The Card-Lok series of retainers offer the highest locking force available for cold wall applications. They mount to Printed Circuit Board assemblies using screws, rivets or adhesive bonding and are then inserted into machined channels of cold plates or heat exchangers. The wedge design holds the Printed Circuit Board firmly in place providing high resistance to shock and vibration while producing maximum thermal transfer.

CHANNEL-LOK For sheet metal or non-machined cold wall applications The Channel-Lok series of locking retainers are designed for heavy shock and vibration, and for effective heat dissipation in sheet metal chassis/heat sink applications. The design combines chassis mounted housing with Card-Lok retainers.

METAL RETAINERS For low cost sheet metal applications or cold wall applications The metal retainers offer a low cost spring action printed circuit board retention design. They attach to the chassis using screws, rivets or adhesives. Retainers provide protection against shock and vibration and offer excellent grounding characteristics.

NYLON CARD GUIDESFor low cost sheet metal applicationsPatented nylon guide entry, easy tool-less installation and snap guides available to support low cost sheet metal card cages.

INSERTER & EXTRACTORMetal and nylon designsCalmark offers a wide selection of Injectors and Extractors for use in both sheet metal and cold wall applications.Available in both metal and nylon designs, these products facilitate the insertion and extraction of printed circuit boards with high density backplane interconnects.

Clamping Force Data - Card-Loks

* Finish is dry film lube over black anodize


Example: A card using a pair of 127mm (5.00 inch) long Card-Loks is clamped to a pair of cold plates and is dissipating 50 watts of power: Total length of Card-Loks is 254 (10), [127 (5) x 2] Junction resistance is shown as between 0.2° and 0.4°C/W Therefore, at their junction, card temperature will rise between 10° and 20°C above the cold plate. [0.2°C/W x 50(W) = 10°C]

Testing performed by numerous users of Calmark’s Series 225 and similar size Card-Loks (approx. 6.35 [.25] high) has shown that the thermal resistance across the interface of a card which is clamped to a cold plate will usually fall within the range of 2° to 4°C inch/watt. Three piece Card-Loks of shorter lengths will usually provide results close to the 2, while longer Card-Loks (over 6 inches) may fall closer to the 4.

These thermal resistance numbers apply when testing is performed at or near sea level. When the same testing is performed at high altitude or near vacuum conditions the results can be significantly affected. Increases of from 10 to 40 percent would not be unusual, especially with the longer three piece Card-Loks.

Five piece Card-Loks, such as the Series 260 or 265, with their greater and more evenly distributed clamping force, will greatly reduce these potential gradients.

The following chart provides an easy method of estimating the temperature rise across the interface (junction) of the card and cold plate when thermal conductivity is the only means of heat transfer considered (heat loss due to radiation and convection minimized).

Inserter - Extractor TheoryBasic theory, knowledge of pertinent forces and understanding of product functionality enables an engineer to select the proper components. The discussion below illustrates the advantage of five or more piece Card-Lok and provides information on how to calculate insertion/extraction forces.

Mc = 0 = FIN (L1 + L2) - FB(L2)

[FB ÷ FIN] = [(L1 + L2) ÷ L2] = C

Example:Calculate the inserter force exerted on the backplane connector when 8.9N (2lbs) finger force is applied to a pair of Series 107 inserter extractors.

FB = C Fin 2 = 4.21 (8.9N (2 lb.)) (2) = 74.9N (16.84 lb.)

Guide to Materials and Finishes Galvanic Corrosion Galvanic corrosion occurs when dissimilar metals are in contact in the presence of an electrolyte (conductive medium). Galvanic com-patibility therefore is important if the application is in an environ-ment where an electrolyte is present. For most office environments this is of little concern. However, if the application is in a marine environment or has contact with outside air then galvanic compat-ibility is necessary. The table below shows a typical galvanic series. In general, the far-ther apart two metals appear on the chart the greater the tendency for corrosion.

Finish Options Beryllium Copper Finish Options (see product pages for ordering information)

• Tin Plate per Mil-T-10727 .0002 min. – Good corrosion resistance but will tarnish over time.

• Nickel Plate per QQ-N-290 Class 1, Grade F – Excellent corrosion protection along with high hardness for wear and

low friction. • Electroless Nickel Plate per Mil-C-26074 Class 1, Grade B

– Excellent corrosion protection along with good electrical conductivity and low friction.

Aluminum Finish Options (see product pages for ordering information) • Chemical Film (Gold) per MIL-C-5541, Class 1A or Class 3 Chemical Film

(Clear) per MIL-DTL-5541, Class 3, Type II – Other commonly used trade names associated with this process

include: Alodine, Alochrom, Iridite. • Anodize (“Soft”), per MIL-8625, Class 2, Type II (.00005” - .0003”)

– Good corrosion resistance with medium abrasion resistance. – Unless specified otherwise color will be black.

• Anodize (“Hard”), per MIL-8625, Class 2, Type III (.002”) – Excellent corrosion and abrasion resistance. – Unless specified otherwise color will be black.

• Electroless Nickel Plate per Mil-C-26074 Class 1, Grade B – Excellent corrosion protection along with good electrical conductivity

and low friction. Stainless Steel Finish • Passivation per MIL-S-5002

– Passivation is not a plating or a coating. It is a cleaning process that removes residue from manufacturing operations and enhances the natural corrosion resistance of stainless steels.
